Im rusty in geo so im giving my best shot

An equalateral triangle means everything by sides and degrees are equal in each other.

The given degrees is (3x-33). Knowing its an equaliteral triangle that add up to 180 in degrees, you can add them up and set them to 180.

it will look something like this : (3x-33)+(3x-33)+(3x-33)=180

simplify: 9x-99=180

x=**31**

**plugging that in, **you know for sure that its correct since all three angles add up to 180.

This x value will be what we need to solve the sides and furthermore AT.

You already know x and that the sides equal to each other so you can just plug in to the given of 9x+69.

which gives line AT=**348**

**hope this helped, and if im wrong, someone please back me up**
